I have hedgehog version of android studio....I did programming of my project in giraffe version but I had to update that version because that was not working also due to some errors i had to update it.....now whenever I am connecting my mobile with my laptop with USB and trying to run the project, the app is not displaying the new changes I made or I am making, it's still showing those old changes.
I tried "clean project, run, rerun, rebuild", I also tried this(https://i.stack.imgur.com/LsxGt.jpg), And this(https://i.stack.imgur.com/dHhFa.jpg)
,And this(https://i.stack.imgur.com/owiyJ.jpg) and all of them...but nothing is working for me.....I want to see all those new changes to appear in my app that I recently made....cuz iam still working on my project ....
